Triple eccentric butterfly valve

The pneumatic triple eccentric butterfly valve is pneumatically controlled. It is suitable for the occasions where the clamp closing or opening time is very strict. With proper accessories, it can be applied to the occasions requiring immediate cut-off. It is a long-life and energy-saving butterfly valve. Its structure adopts the three-dimensional eccentric design principle, and the new processing technology of elastic seal and hard soft multi-layer seal is compatible, which can reduce the torque force of butterfly valve during operation, and achieve the function of labor saving and energy saving. So as to ensure the overall reliability of corrosion resistance, high temperature resistance and corrosion resistance. It is suitable for food, medicine, petrochemical, power plant, steel plant, industrial environmental protection water treatment, high-rise building, water supply and drainage pipeline as the best device for regulating flow and cutting off fluid.
Product features:
1. Small volume, light weight, excellent cutting performance.
2. The sealing surface of butterfly plate is designed to be a conical surface with oblique section relative to the center of butterfly plate, so that there is a certain contact angle between the sealing surface of butterfly plate and the sealing surface of valve seat. The contact angle is uniform around its circumference, which is equal to a slender wedge, and the sealing line at the longitudinal position of the butterfly plate circumference presents a quasi elliptic curve, both of which play a sealing compensation role at the same time.
3. When the butterfly plate is closed, the force is uniform and the pressure bearing capacity is high; when the butterfly plate is opened, all points on the sealing surface of the butterfly plate can be separated from the sealing surface of the valve seat at the same time, and there is no jamming phenomenon, basically no friction, and the opening torque is very small. Therefore, the utility model has the advantages of low cost, good sealing performance and long service life.
4. Various sealing structures are available to ensure service life and reliability. Butterfly valve seal ring has integral soft seal (PTFE, c-tfe, g-tfe), hardened metal plate, integral + cemented carbide, suitable for various working conditions.
5. It can realize bidirectional sealing function, which can be adjusted and cut off.
6. The actuator has low friction force, high efficiency, high thrust and good safety.
7. The design of smart and combined actuator (manual mechanism) can ensure the random installation and flexible control in all directions.
8. Simple and eye-catching, reliable and integrated travel indication, combined installation of limit switch and solenoid valve, no external pipeline and less leakage points.
9. A variety of actuator forms can be selected to meet the requirements of different users.
10. Assembly and maintenance is convenient, with superior performance price ratio.
